It takes 3 years for the balance of account to be $ 221

<em><u>Solution:</u></em>

From given information,

Principal = $ 200

Rate of interest = 3.5 %

Amount after "n" years = $ 221

To find: number of years

In simple Interest,

Simple interest = amount earned - principal

Simple interest = 221 - 200 = 21

Thus simple interest earned is $ 21

<em><u>The formula for simple interest is given as:</u></em>

simple\ interest = \frac{ p \times n \times r}{100}

Where,

p is the principal

n is the number of years

r is the rate of interest per annum

Substituting the given values in formula,

21 = \frac{200 \times n \times 3.5}{100}\\\\21 = 2n \times 3.5\\\\n = \frac{21}{7}\\\\n = 3

Thus it takes 3 years for the balance of account to be $ 221

We know that

<span>a) the slope-intercept form of the line---------------> y=mx+b
b) </span><span>if two lines are parallel both have the same slope
</span>then
<span>passes through the point (1,0) and is parallel to x-y=7

Step 1
Find the slope
</span>x-y=7------------> y=x-7------------> m=1

Step 2
Find the slope-intercept form of the line---> y=mx+b
point (1,0)  m=1
0=(1)*(1)+b------> b=-1
y=(1)*x-1--------> y=x-1

the answer is 
y=x-1
